Product detail
The DNT Hydra HS635 is equipped with a 12μm ≤18mk thermal 640x512 pixels sensor for ultra-clear thermal images, and DNT's proprietary Super Resolution image algorithm just made the impossible, possible. This amazing technology now enhances your thermal image to the next level and resolves the biggest issue of thermal losing definition after digitally zooming in. Notably, its 1.5-6x(1.5x,2.25x,3x,4.5x,6x) continuous digital zoom captures fine details in total darkness, ideal for nocturnal hunting and surveillance. Engineered with magnesium alloy housing, this scope withstands extreme weather (-20°C to 50°C), while its IP67 rating ensures reliable performance in rain, fog, or dust. Standalone Scope + Clip-On + Handheld Monocular, Hydra redefines the standard for the thermal industry. This is one of the most capable and best-valued thermal ones you can imagine. CNC machined from an entire block of aircraft-grade aluminium, Hydra is extremely sturdy for all environments. The side-mounted joystick and ergonomic focus wheel enable single-hand adjustments, minimising disruptions during high-stakes operations. For enhanced versatility, six imaging modes (White Hot, Black Hot, Red/Blue Monochrome) adapt to environments from forests to urban rooftops. A proprietary AI image stabilisation reduces motion blur during dynamic tracking, critical for fast-moving targets. The removable 4-hour battery supports extended missions, and direct USB-C charging ensures rapid power-ups. Built-in Wi-Fi streams live feeds to mobile devices, allowing real-time coordination in search/rescue scenarios. Our Hydra thermal scope is equipped with a 12μm ≤18mk thermal sensor for ultra-clear thermal images, and DNT's proprietary Super Resolution image algorithm just made the impossible, possible. This amazing technology now enhances your thermal image to the next level and resolves the biggest issue of thermal losing definition after digitally zooming in.

Buyer guidance
Choose it for the right job
Plain, practical checks for UK buyers comparing thermal, night vision and rifle optics before paying.
Close pest control
Rats around buildings or feeders are usually short range. Prioritise a clear image, quick start-up and easy handheld handling before chasing maximum distance.
Rabbit and fox work
For rabbits and foxes, check realistic identification distance, LRF needs and battery life. A higher sensor and suitable lens matter more than bold marketing range claims.
Mounting check
If it is going on a rifle, confirm the tube, mount or rail fit before payment. Common checks include 30 mm / 34 mm rings, Picatinny or dovetail fittings and eye relief.
Compatibility checklist
Useful details to confirm before payment, especially for rifle-mounted optics and add-ons.
- Intended use: rats, rabbits, foxes, target shooting or observation
- Typical distance: under 50 m, 50-150 m, 150-300 m or longer fields
- Mounting: 30 mm / 34 mm tube, Picatinny, Weaver, dovetail, clip-on or handheld
- Accessories: IR illuminator, battery pack, charger, rail, case or tripod
